Understanding the Problem

Mathematics plays a crucial role in understanding various real-world phenomena, including the behavior of water in a pool. In this article, we will delve into the given table, which shows the gallons of water in a pool over time. We will analyze the data, identify patterns, and use mathematical concepts to make predictions about the future behavior of the pool's water level.

The Given Table

Time (min)	Water in Pool (gal)
0	50
1	44
2	38
3	32
4	26
5	20

Analyzing the Data

At first glance, the table shows a decreasing trend in the water level of the pool over time. The initial water level is 50 gallons, and it decreases to 20 gallons after 5 minutes. This suggests that the pool is losing water at a constant rate.

Calculating the Rate of Water Loss

To calculate the rate of water loss, we can use the concept of slope. The slope of a line represents the rate of change of the dependent variable (in this case, the water level) with respect to the independent variable (time).

Let's calculate the slope using the first two data points:

m = (y2 - y1) / (x2 - x1) = (44 - 50) / (1 - 0) = -6 / 1 = -6

This means that the pool is losing 6 gallons of water per minute.

Predicting the Future Behavior of the Pool's Water Level

Using the calculated rate of water loss, we can predict the future behavior of the pool's water level. Let's assume that the pool continues to lose water at the same rate.

After 10 minutes, the water level will be: 50 - 6(10) = 50 - 60 = -10 gallons

This is not possible, as the water level cannot be negative. Therefore, we can conclude that the pool will be empty after 10 minutes.

Conclusion

In conclusion, the given table shows a decreasing trend in the water level of the pool over time. By analyzing the data and using mathematical concepts, we were able to calculate the rate of water loss and predict the future behavior of the pool's water level. This example demonstrates the importance of mathematics in understanding real-world phenomena and making predictions about future events.
